Not illustrated. 1884 Excerpt: ...rear end of the furnace, 50 feet in height, and circular in form, 8 feet in diameter. The fresh air enters the mine through another shaft, 47 feet in depth, and located on No. 2 butt entry. The head of the present workings is nearly one mile from the pit mouth. The main hauling roads are laid with "T" iron rails. The main entry and air course are driven parallel with each other, approximately N. 20 W., with 40 feet of solid coal remaining between them. They rise about 66 feet from the pit mouth to the mouth of No. 20 butt entry, a distance of 1720 yards, and are still rising so far as driven. A swamp enters this mine at the north side from the Cliff mine, on a bearing of about S. 65 W. and passes through the head of the old workings, where it curves to the north-west and pursues a direction approximately parallel with the main entry. It crosses butt entry No. 16 at 520 yards from the main entry, and is 25 feet in depth at that point. The roof members are much disturbed bv small horse New Coal Bluff mine Section No. 1.

Clay veins and spars are quite numerous, but are not so large as to cause any serious inconvenience in mining. There are a few rolls in the roof member that cut out almost all of the over-clay for short distances. Near the mouth of butt entry No. 17 I found the lower coal members to measure: Roof coal.
